Answer explanation

Why can you never trust a math teacher holding graph paper?

They must be plotting something!

Solve:

3x - y = 11

x + y = 5

• x = 4

  y = 1

• x = 4

  y = -1

• x = -4

  y = 1

• x = -4

  y = -1

Solve:

2x + 3y = 5

x + 3y = 7

• x = -2

  y = 3

• x = -2

  y = -3

• x = 2

  y = 3

• x = 2

  y = -3

Solve:

3x + 5y = 4

4x - 5y = -18

• x = -2

  y = 2

• x = -2

  y = -2

• x = 2

  y = -2

• x = 2

  y = 2

Solve:

2x + y = 16

4x - y = 2

• x = 3

  y = 10

• x = -3

  y = -10

• x = -3

  y = 10

• x = 3

  y = -10
